As previously stated, the links l5 and It are wider than the links I3 and I4 in order that the latter may be received within the overlaping arms of the former, as shown in Figures l and 2. The clamping plates Il receiving the crossed links l5 and i6 are similarly held together by a screw 31 passing through ahole 38into a threaded hole 39. y,

In the operation of the night conveyor ofV the invention, the conveyor l0 is made up in the form of an endless chain supported and guided `by grooved pulleys or the like andY passingV through tubular conduits. One of the Ipulleys is driven by a motor or other suitable source of power through appropriate reduction gearing. The details of the driving and guiding arrangements form no part of the present invention lbut are fully disclosed in my co-pending application, Serial No. 485,707 nled May 5, 1943 for Flight conveyors, of which the present application is a division.

As the night conveyor l0 moves through its conduit and passes a suitable feeding aperture or hopper, it receives a charge of the material to be conveyed. The material falls between the nights l l and is carried alongby them, the annular sealing members 32 engaging the Walls of the conduit and preventing leakage or slippage of the material.

From Figures l and 2 it will be observed that the alternate pintle pins 2l in the night conveyor lo are perpendicular to one anothelnthereby pivoting the alternate sets of U -shaped links to swing on mutually perpendicular pivot axes. By reason of this construction, the' flight conveyor l0 can move laterally in either of two directions, thereby enabling it to negotiate bends in the conveyor conduit or turns on the conveyor pulleys, regardless of their positions or relative arrangement. This construction therefore imparts great nexibility to the conveyor and enables it to be adapted to any peculiariti'es of the particular installation such as negotiating obstacles in a like, in which the conveyor is to be installed,

For installations where an annular rubber or synthetic rubber insert 32 is unsuitable, such as in conveyors for handling high temperature ny ash in heating or power plants, an annular metal insert 32 may be used in its place.

What I claim is:

l. A night conveyor comprising an endless'nexible conveying member, a series'oi conveyor nights connected to said member at intervals therealong, each of said conveyor flights including a pair of clamping members having plate-like portions secured to one another 'in abutting relationship and having peripheral portions onset axially in opposite directions relatively to one another to form a continuous peripheral recess, and a wear member disposed in said recess.

2. A night conveyor comprising an endless flexible conveying member, a series of conveyor nights connected to said member at intervals therealong, each or" said conveyor nights including a pair of clamping members having plate-like portions secured to one another in abutting relationship and having peripheral nanged portions offset axially in opposite directions relatively to one another to form a continuous peripheral recess, and a wear member of elastic deformable nmaterial disposed in said recess.

3. A night conveyor comprising an endless nexible conveying member, a series of conveyor nights connected to said member at intervals therealong,

each of said conveyor nights including a pair of clamping members or cup-shaped form having plate-like portions secured to one another in abutting relationship and having annular peripheral portions onset axially in opposite directions relatively to one another to form an annular peripheral recess, and an annular wear member disposed in said recess.

4. A night conveyor comprising an endless nexible conveying member, a series of conveyor nights connected to said member at intervals therealong, each'of said conveyor nights including a pair of clamping members having plate-like portions secured to one another in abutting relationship at their central portions and having annular peripheral portions offset axially in opposite direcbuilding, tank or the k tions relatively to one another to form an annular peripheral recess, and an annular wear member of elastic deformable material disposed in said recess.

5. A night conveyor comprising a series of conveyor nights, each night including disc-like'clamping members secured to one another and having oppositely offset peripheral portions forming an annular peripheral recess therebetween, said clamping members having spaced pairs or apertures therethrough, U-shaped links projecting through said apertures from opposite sides or said nights, pivot elements interconnecting the free ends of said links, and an annularwear member disposed in said peripheral recess.

6. A night conveyor comprising a series of conveyor nights, each night yincluding disc-like clamping members secured to one another and having oppositely offset peripheral portions forming an annular peripheral recess therebetween, said clamping members having spaced pairs of apertures therethrough with one pair of apertures in each night disposed perpendicular to the other pair, U-shaped links projecting through said apertures from opposite sides of said nights, pivot elements interconnecting the free ends of said links and an annular Wear member disposed in said peripheral recess. Y

'7. A night conveyor comprising a'series of conveyor nights, each night including disc-like clamping members secured to one another and having oppositely on set peripheral portions viorming an annular peripheral recess therebetween, said clamping members having spaced pairsof apertures therethrough with one pair of apertures in each night disposed perpendicular to the other pair, U-shaped links projecting through said apertures from opposite sides of said nights with the central portions of said links crossing one another on opposite sides of said nights, pivot elements interconnecting the rree ends of said links, and an annular wear member disposed in said peripheral recess. j

8. A night conveyor comprising a series of conveyor nights, each night including disc-like clamping members secured to one another and having oppositely `offset peripheral portions forming an annular peripheral recess therebetween, saidiclamping members having spaced pairs of apertures therethrough, U-shaped links projecting through said apertures from opposite sides of said nights, pivot elements interconnecting the free ends of said links, certain of said links being widerr than and overlapping other links at their free ends, and an annular wear member disposed in said peripheral recess.
